新型负压吸附式烤烟漂浮育苗简易播种器的研制与应用

目前烤烟育苗多为手工播种，费工费时，为了有效降低用工成本，提高劳动效率，满足新形势下烤烟漂浮育苗集约化、规模化、机械化的需要，设计了一种负压吸附式烤烟播种器。该机利用空气负压原理，通过精确打孔的播种盘吸附和释放烤烟种子，实现精准快速播种。据此理念结合实际应用，提出设计方案并试制了样机。通过检验，该机操作简便，播种精度好，播种效率高，较对照节省播种时间45.9%~83.9%，出苗率在92%以上，作业质量符合烟草播种育苗要求。

Development and Application of New Simple Aspirated-air Type Tobacco Planter

Currently tobacco seedling relies on manual planting, which is time and labor concuming. In order to effectively reduce labor cost, improve labor efficiency, and satisfy the need of seedling intensification, large scale, and mechanization under new situation, an aspirated-type tobacco planter was designed. This machine used the principle of negative air pressure, absorbed and released tobacco seeds with precise punching seed tray, to realize accurate and fast planting. According to this concept and combined with the pratical application and cost keeping, a design plan was forward and a model machine trial was produced. Through test, this machine was found easily to operate and sow with fine accuracy and high efficiency. It could save 45.9%~83.9% sowing time compared with the contrast, and the germination rate was over 92%. The seeding quality was accordance with tobacco sowing and seedling.
